TRNSYS Types (free of charge according to license agreement)
ISFH components for thermal system simulation with TRNSYS
ISFH has developed a series of components for the representation of thermal and electrical system technology for the simulation environment TRNSYS. We provide a selection of the generated types free of charge.
How do I get such a type? Please download the respective license agreement and fax it filled out with your e-mail address to 05151-999-500 or send it to firstname.lastname@example.org. We will then email you the type.
|TRNSYS-Type 203 for uncovered PVT collectors
The PVT collector type 203 describes the thermal and electrical behaviour of uncovered PVT collectors and was developed in the BiSolar-WP project. The parameterisation is carried out exclusively via characteristic data of common standards for PV modules or solar thermal collectors.
Licence agreement type 203
|TRNSYS-Type 708 as a casing for buried storages
Type 708 describes the thermal behaviour of the surrounding soil of buried storages and was developed in the project KES (small buried storages).
Licence agreement type 708
|TRNSYS-Type 292 as volume flow correction for heat pump types with characteristic diagram
Type 292 performs a volume flow correction for heat pumps with characteristic diagram and was developed in the Geo-Solar-WP project.
Licence agreement type 292
|TRNSYS-Type 204 for oil or gas boilers
Der Type 204 calculates the transient behaviour of oil and gas boilers and was developed in the WE-Sim project.
Licence agreement type 204
SCAN - Solar cell analysis (for a fee)
SCAN (Solar Cell Analysis) is a computer software that analyzes measurement data from wafer-based crystalline silicon solar cells. In addition to widely used analysis methods such as the evaluation of the current-voltage characteristic (IV), the quantum efficiency (QE) and the reflection or capacitance-voltage measurement (CV), image-based evaluation methods such as the determination of the local series resistance (EL/PL) or the local shunt resistance (LIT) are also available.
SCAN requires a Windows-based computer (Windows XP or higher) and runs on all desktop PCs as well as laptops. It is tested and used within ISFH. SCAN has been developed and continuously improved since 2007.
SCAN is now available for purchase Please contact Dr. Karsten Bothe for more information and a quote.

SEGA GUI (free of charge according to license agreement)
In the research of industrial silicon solar cells the gap to the theoretical efficiency limit of about 29% closes gradually. State-of-the-art industrial PERC cells achieve efficiencies around 22% leaving only 7% efficiency improvement potential. Closing this gap further is a challenging task for cell developers. The identification of the most promising cell properties for the further research is an important aspect of the development process. The SEGA-GUI, which can be downloaded below, addresses this task by enabling researchers to perform synergistic efficiency gain analyses (SEGA) without any programming knowledge and on short timescales. Here the solar cell is simulated one time with the parameter as in a reference simulation and one time with the parameter idealized. The difference of the energy conversion efficiencies is the improvement potential due to this parameter. This approach also enables the analysis of synergistic effects between different loss channels. Also partly deactivated loss channels can be analyzed. The input required for performing a SEGA is a set of easily measurable cell properties including resistances and recombination currents. The optical properties of the cell can be determined from a measured reflectance spectrum.
